Kenneth Aubin, 62, was pronounced dead at the scene. He was wearing a helmet.

No one saw the rollover, said Const. Bev Gauthier. Its cause is still under investigation by technical traffic collision investigators from the Sault and East Algoma OPP detachments. A passerby found Aubin.

He was with a hunting party. Aubin woke up, left the group and went riding on his ATV, said Gauthier.

A post-mortem will be done. Time and location were not available Friday.

Aubin's death is the third recreational death in Algoma District since early August.
